Hello there, I am Chandan Chaudhary, from Mumbai India. I make websites, mostly on wordpress platform. I've written several custom plugins for clients as well as few available to public in wordpress plugin repository.

I am normally always occupied with work, but if you have an interesting project, i'd be glad to discuss it.

You can find me on:

Below are posts I've written:-

Hide specific posts/pages/cpts from guest users in WordPress

Hide pages/posts/custom post types from guest users in WordPress. The setting can be done on per page/post basis.
If you wanted to hide just a couple pages from guest users, but want it to be available for members, you can use this plugin.

  1. Download this plugin.
  2. Upload and install it via wp-admin plugin installer. Activate the plugin.
  3. A checkbox will appear on edit page screen now:
    Restrict access custom field
    If you check the checkbox, this page will not be viewable unless user is logged in. Guest users will be redirected to login page when they try to view this page.
  4. By default, this checkbox only appears for ‘pages’ and not for ‘blog posts’ or any other custom post types that your website might have. It is however very easy to add it for other post types as well. For example, if you want it for custom post type called ‘course’, you can put the following code in your theme’s functions.php file:
    add_filter( 'restrict_access_post_types', 'myprefix_restrict_access_post_types' );
    function myprefix_restrict_access_post_types( $post_types ){
    	$post_types[] = 'course';
    	return $post_types;

WordPress multisite forgot password url issue

Forgot password/Lost password link in login form on subsite in a WordPress multisite setup has an issue. The link points to main site and not to the subsite where user is actually trying to login.
If the visitor is at, forgot password link here will point to This might not be desired in some situations.

Additionally, the email sent for password reset action, also has login links to main site in network and not the subsite where user was actually trying to login.

Javascript recursion example

Everyone loves(or should i say ‘gets intimidated by’?) Recursion. But it can be confusing to begin with. So here’s an example of recursion ( in javascript ) to show how recursion can be used to solve real problems in real projects 😉 . The code below is an altered code from one of my projects. Although its in javascript, the basic principle is same and can be easily reproduced in any other language of your choice.

Hope it helps..

bbPress Tag Cloud Widget

A very small wordpress plugin. If you’ve been using bbPress plugin, you know that it provides a shortcode to display the topics-tag-cloud. I’ve wrapped that into a small widget, so one can just easily display the tag cloud wherever required with just drag-and-drop.

You can download the plugin form its github repository.
**Note: Github adds the word ‘-master’ into the plugin’s folder name, so uploading the zip file (downloaded from github) directly to install the plugin won’t work. So, just rename the zip file to

That’s it here.
